I side plate of the vertical totalixer truck is connected with and partially supported by the typewriting carriage so as to travel toward the right and toward the. left with said carriage. The uppe' roll 32 has a vertical rbor journaled in an overhanging bracket 33 projecting from the casting 18. Any suitable number of vertical totalizers can be mounted side by side on the truck 31. In the presenhinstance I have shown two totelizers 34: and 35 and two dummies 36 and 37. Each of these cinmmies consists merely of the frame. work of the totalizer with the computing mechanism omitted. and they are put onto the machine in order to co-ogerute with the cross totalizer. These dummies may if preferredhe replaced with complete totalizers. Each totulizer or dummv secured pressed latch 38 4:0. In order toavoid con drawings these latches are omitted from the diagrammatic view (Fig. lCzu-h of them includes an orcr-hanging finger piece "ii and a spring loop which may be pivoted to the top of the tot-ali'lzer at 43 and when the totalizer is in position on the carriage-this loop can beswung around'unclcrneath the finger piece ll and exert a still upward spring pressure to hold the latrh 38 more firmly in place.

Each of the totalizers oi the ordinary lVahl construetionend includes dial wheels 44 and carryingwiieels 4-5. (Fig. l) the latter adapted'to be driven by the main master wheel 46. Said master wheel constitutes part of a main actuator which actuator is operated by well known means from the numeral keys 17 with which it connected by means o links Feh vertical totalizer has on its upper casin .1 decimal stale with which a pointer -28 oo-operates. said pointer being mounted on the hrackei 2323.

The cross footing carriage consists of a small truck 50. (Fig. 4) traveling: by means of ball bearings 51 in the casting 24 and. drawn toward the right by a long tension spring 52 running over a pulley 53 (Fig. 5). -Said truck has a totalizer 54 mounted thereon. its'latch 38 cooperating with a plate 55 secured to the truck 50 and having therein a single notch. 54 is operated by a cross footing actuator comprising a master wheel The truck 50 normally stands in its extreme'ri zht-hand position but on occasion it is picked up by the vertical totalizer-s and dummies by means of a hook 5t; pivoted at 57 to a bracket 58 secured to said truck. Said hook a luv 60 (Fig. 4) on the is also engaged on its opposite side by a dotent 61 (Fig. l). The truck is drawn to the left in the writing and calculating of The totalizer' a number until the last carrying wheel $5 is in engagementwith the master wheel 59. At the next step of the carriage the hook 56 is disconnected and the cross footing truck is drawn to the right by its spring 52 until it is arrested in l'lOlflillll position by means of an adjustable stop bar tlilsecured to the truck, said bar striking a lcrer (53 and moving said lever over against the frame plate 2i. This sometimes railed a. jumping totalizer. in some Inaehin as in the present one, it is the totalizer itself that jumps and in other machines it'istho master wheel. etc. that jumps. Said lever 63 is pivoted at (it infill car oi the plate 21 and it is provided t Mi. a spring: 62' tending to swing said lever to the left to the p in l ig. 53. l shall iind it convenient torefe: to this'iev. o as loc 1" S .J suitable slot in a slide hul'tiiiri it. iiiived a shortdtsluuce Eta orto it right by the motion oi ti tiLl. Fiaid link is guided in the frame plates oi the cross footer and at its ieft'hand end it has a crotch that embraces the dependingarm of a hell crank 67 pivoted at (38 iii the stationary framework, The horizontal arm of the bell crank 67 has a blocking det'ice TO ')li'(liL(l thereto at Tl and lying against the iorward end of a fixed post 72 having a longitudinal slot. Til in its under-side. The construetion is such that when the lever Gil is in hand position. as shown in 5 t blocking plate 70 stands at an el above the slot. T3: but when the said lever moved to its right-hand position this blockin g plate moves down low enough to rover up the end of said slot.

The l a horizontal arm thereof. which roller is normally held in air upper position by means of a spring til but which. when a vertical totalizcr is over the master wheel 46, is adapted to be depressed by a track or rail 8'2 mounted in said vertical totalizcr. The wliolc.ionstruction is such that when there is no vertical tot alizer over the master wheel 46 then the plate 70 is swung so far to .the left as not. to lie able to cover the slot 73 in the post 72; but when a vertical totalizer is over the master wheel then said plate is swung to the right 'lar enough to cover said slot. This is a well known lock in use in the Remington lvahl machine and described in which lug; the patent hereinhefore referred to. it will be perceived that it is so constructed that the plate Ttl can never block up the opening to the slot 73 except when a vertical totalizer rame T? has a roller fit) on magma g3 over the master wheel and it is also so com structed that said plate cannot block up said opening,- ertcept when the lever 63 is in its right-hand position, so that it requires a combination of two conditions to cause said plate to block up said slot.

Comprised within the main actuator is a universal bar 83 (Fig. 2) consisting of a roller turned in certain arms 84 rigidly mounted on a universal rock shaft 85. The

linlcs 7 actuate certain devices 190 (Fig; 15) sometimes called fans, each of which is adapted to engage the universal bar 83 and swing it toward the front of the machine time rocking the shaft 85. Said shaft has an arm 86 rigidly projecting therefrom in such position that when the shaft isrocked as described this arm moves into the slot '73. This it is always free to do except when, under the above mentioned coi'nbination of conditions, said slot 73 is blocked by the plate 70. In that event the shaft and the universal bar 83 are locked against; move ment and the keys are therefore locked against depression and the operation of the machine cannot be proceeded with until the plate 70 shall have been moved awalv from the slot 73. I have described this cl: in. some detail because it is already present in the machine and I find it convenient to use it in connection with m clearance proof mechanism, but it will 0 course be understood that any other suitable means for locking some essential-part of the mechanism would answer my pur ose.

In the lVahl machine as manufactured and as described in. the atenthereinbefore referred to the rock sha t 78 has anarm 87 projecting-leftward tlierefrom and carrying a roller 88 adapted to cooperate with cams 90 mounted on the framework of certain of the vertical totalizers and F dummies Said arm is urged upward to a limited extent by aspring not shown herein and when it is in its uppermost position the master wheel 59 of the cross footer is connected up for addition. When said arm occupies its lowest position said master wheel is con? nected up for subtraction and when itoccupics an intermediate position the master wheel 59 is not connected to the balance of the actuating mechanism so that the cross footer is inoperative. This arm therefore has a normal elevated position in which the cross footer is set for addition; a middle position in which said cross footer is discounected, and a lowest position in which the cross footer is set for subtraction. Thedetails of this automatic control of the state of the cross footing actuator are fully disclosed in the patent above referred to.

The machine can be set in various ways to perform over and over again a regular program of writing and calculation, and one instance of such a setting is diagrammatically .the platen 15 the first operation is to write the old or piclr-up--balance in the fourth column. Usually this is written on the same line as the old balance which had been writ ten in the third oolumn at the next preceding operation on that particular ledger sheet. The operator, therefore, when the paper is put into the machine turns the platen 15 to bring the last written line to the writing; line and in column-4t copies the balance seen just to the left of it in column 3", The paper is then line-spaced and the carriage drawn back to begin a new line of writing. The debtor item then written in column I, and the creditor item in wlumn 52, and the resulting balance is then. written in coiunm 3, and this is the end of the pro-' gram, If there is more than one deb creditor item to be entered the paper i spaced and the second item written under the first, but in ,very case the writing of the new balance in column 3 is the last ation on that particular sheet at that particular time. This sheet is then removed from the machine and another sheet insert ed and a. similar program gone through with. In Fig. l the parts are shown in position for writing the digit of lowest order in the third column, and the next keystroke, to write said digit, will end the program. This last keystroke will cause the carriage to step one space to the left, and the cross-totalizer to be freed and allowed to snap ba k to its extreme right-band position, or at least as far as dummy 37 will allow it to go. i l/hen the next ledger sheet put into the n hine the carriage is already in positio ahead and copy in the picheap-balance for that sheet.

In the program describe-fl the calculation of the new balance is etltcted on the cross lotalizer 54-, and this is accomplished by causing the pick-uplialance written in col umn t to he added into said cross totalizer, and the debtor item written in column 1 to he also added in said cross totalizer, and the creditor item. written in. column to be subtracted in said cross totalizer. At this time said cross totalizer will show the new balance and if said cross totalize'r is set for subtraction when copying. the new balance in column 3, the copying of said new balance. if correctly done, will bring said cross totalizer to zero. In this program, therefore, the cross totalizer should always stand at icoiic

It wili he perceived that by" the described means the lock is tl'aro'v ii in every time the totslizer or dun'miy 36 passes to its sub-units position as in the first form of the invention. In the presentv form of the invention the mechanism is unlocked by depressing the bar 154 by hand. To this end a lever 176 (Figs. 13 and 1:1) is loosely pivoted on a shaft 160 between. the right-hand hub 158 and the fixed collar 1?? The arm 157 of the lazev or hand operated bail 154 has a log 178 bent oil therefrom and lying over-the forward end of the lever 176 so that when the her that in case the bar 154 is depressed the lever 176 will rock with said bail. The rear arm of said lever 1-76 lies beneath the bell'ersnl; 163 which will therefore be moved. to unlocking position when the bail is operated. Seid lever 17% is prolonged toward the res end terminates in' it handle here shown as having the form of knob 180. The COZlSi'fiHCeiQH is such looked the operator can put his finger underneath the knob 180 and operate the lever 176 lI'LdPr pendeiitly of said her and it is for this reason that said lever is looselv pivoted on the shaft 160 A spring 181 is coiled about id shaft 160 and at one end it is connected with a pin 182 projecting from the shaft, and. at its other end it hears against 21 pm 183 profleeting from the lever 17th the force of this spring holding: said lever in its normal relotion to the bail that is to say, with the forward end of the lever pressed against the lug 178. The rear arm of the lever has a log 18?: (Fig: 13; adapted to engage the upper surface of the casting or which is here shown machined-ell? at the proper point for the purpose. The pin 182 projects from both of the shaft 160 and a second spring 185 is coiled about the end of the shaft and hooked over said pin. at one end and in its other end is passed through a hole 186 (Fig. 9) in the bracket 181 The foree of this spring tends to elevate the finger her 154% 'lhis however it is inito do beyond the" point where the strikes the casting 4 for the reason ssicl spring 185 is thereafter unable The bar 15% can however he swan iii place e totelizer on said truck, on operw lion which Woold oizherivise be more or interfered with by the bail. Upon releasing: the bail after such an elevation of it is restored to its normal position the spring 181 and on depressing the bail it is raised to its normal position by the sgsririg 185.

The mode of operation of this for i of the invent-ion is as follows: When the carriage reaches the sub-11nits position of the totah izer or dummy the cam 111 (Fig. 3} operates the hell creel; 97, 9S pushes the Wire 1130 momentarily toward the left, tripping the [arch lever 3.62, 163 and ellov ing the lever 166 to swing about its pivot and the pin 171 to operate the locking lever (530. At the some time the cross footer is freed and jumps baek to the right.
